Authenticate with an API key or OAuth flow, assign the proper scopes for scheduling, contacts, and customers, and store credentials securely.
Authorize Acuity Scheduling to access your GHL data by following the OAuth flow or using a generated API key, depending on your setup.
A comprehensive list of GHL endpoints used in this integration includes {API Endpoint1} through {API Endpoint54}. Not all endpoints are required for every page.
Trigger: When an appointment is created or updated in Acuity Scheduling, push the change to GHL to keep calendars in sync.
Actions: Create or update the corresponding appointment in GHL, and refresh related contact records.
Method path: /appointments
Key fields: appointment_id, start_time, end_time, customer_email, status
Trigger: New or updated contact data in Acuity Scheduling updates GHL contacts.
Actions: Create or update contact in GHL; associate with related appointments; sync notes.
Method path: /contacts
Key fields: contact_id, email, first_name, last_name
Trigger: A new lead in Acuity form submission creates or updates a lead in GHL.
Actions: Create opportunity in GHL; link to the lead; update source and status.
Method path: /leads
Key fields: lead_id, source, status
No‑code automation lets you connect apps and automate scheduling without writing a line of code.
Visual workflow builders and webhooks empower rapid setup and maintenance.
Centralized data syncing reduces manual data entry and errors.
This glossary defines common terms and processes used throughout the integration guide.
A set of endpoints exposed by GHL that lets external apps read, create, update, and delete data programmatically.
An authorization framework that lets apps access user data securely without sharing passwords.
A token used to authenticate requests to the GHL API.
A callback URL that receives real-time updates from GHL when data changes.
Keep both calendars aligned by mirroring appointments in real time.
Automatically route new inquiries to the best agent and schedule follow-ups.
Push status changes and reminders to clients through GHL notifications.
Generate API key or OAuth client in GHL and store securely.
Map fields, set webhooks, and test calls to Acuity Scheduling.
Run validation tests, verify data integrity, and enable automation in production.
No heavy coding is required for this integration. The Custom Menus API provides a visual workflow approach to map Acuity Scheduling data to GHL endpoints. If you can configure webhooks and field mappings, you can connect these systems without writing server-side code. For complex logic, you can still add small scripts or use Zapier as a bridge.
Both API keys and OAuth are supported, depending on your security policy. Use OAuth for user-based access and API keys for server-to-server flows. Ensure the scopes cover appointments, contacts, and leads.
Common endpoints include /appointments, /contacts, and /leads. The exact endpoints depend on your chosen setup. Use the endpoint list to reference required calls in triggers and actions.
Yes. Field mappings let you control which fields sync and how. You can transform data during transfer and choose which fields to quarantine or ignore.
Real-time streaming via webhooks is supported, but there can be slight delays depending on network conditions. For critical workflows, implement retries and logging.
Yes. The no-code approach uses the Custom Menus API and Zapier App Connector to connect Acuity Scheduling and GHL without custom code.
Logs and error messages appear in your Zapier runs or GHL console. You can enable webhook retries and view error details in each integration step.
Due to high volume, we will be upgrading our server soon!
